A Link between Trust in Technology and Glance Allocation in On-road Driving

This paper examines whether there is an association between preexposure
trust in technology and subsequent glance behavior when interacting with
a technology that was relatively novel for the majority of participants. After rating
their level of trust in technology on a questionnaire, participants drove one of two
vehicle models on a highway and engaged in a voice-based navigation address entry
task. Subjective ratings of trust in new car technologies were found to be
significantly positively correlated with a higher frequency of glances across all
coded glance regions during the task. In one of the voice-interface implementations,
these higher ratings of trust were also associated with a higher frequency of glances
to the user interface, but with fewer long duration (>2s) glances per minute. A lower
trust in technology in general showed some association with taking more time to
complete interactions. The findings are discussed as highlighting the potential value
of further research into the associations between trust and visual scanning behavior.
